MACHINEFOR MOVING RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 527,374, dated October9, 1894.

Application filed July 18, 1894. Serial No. 517,845. (No model.)

To all whom t may concern:

Be it known that I, EDUARD W. RINGRosn, of the city of Baltimore andState of Maryland, have invented certain Improvements in Machines forMoving Railway-Cars, of which the following is a specification.

In the description of the said invention which follows, reference ismade to the accompanying drawings forming a part hereof, and in which-Figure 1 is an exterior side view of the in* vention, together with apart of a car wheel to which the invention is applied. Fig. 2 is a planof Fig. l. Fig. 3 is a rear end view of Fig. 1. Figa is a front end viewof the apparatus without the car wheel. Fig. 5 illustrates amodification in the construction of a part of the machine.

Referring to the drawings, A is a frame formed, principally, of twoplates a.

B is a spindle which passes through bosses on the plates a to support arevoluble disk C. This disk is toothed at its edge or circumference, theteeth being denoted by b; and on its sides are formed annularprojections c having ratchet teeth d on their edges. On the faces of theannular projections c are cast beveled teeth e in gear with beveledpinions D which form a part of corrugated tapered rollers E. Thegudgeons f of these tapered corrugated rollers rest in bearing boxes gcast integral with the frame plates a.

From the foregoing description it will be understood that when the diskGis turned -in the direction indicated by the' dotted arrow i in Fig. l,the tapered corrugated rollers E are turned as indicated by the arrowsinfull lines; and when the machine is applied to a car wheel F, that is tosay, brought so closely in contact with the said wheel as to make thetapered rollers grip the flange and tread of the wheel, and placed inoperation, the wheel is turned and the car moved.

The means for turning the disk and its wheels, consists of a socketGhaving arms extending therefrom connected to the plates a ofthe frameby means of the spindle B which passes loosely through them. The socketG has a double spring-held pawl H which e11- gages with the ratchetteeth d and is pivoted between the arms of the socket G. Within thesocket G is inserted a hand-bar I, a portion only of which is shown.

The frame A is provided with two rollers J and K which support it on oneof the railsP of the track, and the roller J has recessed spur teeth cin engagement with the teeth b of the disk O. By this arrangement, whenthe apparatus is in use it is propelled forward and made to follow theretreating car wheel. The other roller K is merely to support the frontend of the apparatus.

L is a lever pivoted at m to the frame A and curved so as to passpartially around one of the tapered corrugated rollersE. At the upperend of this lever is an arm 'n with a square hole o therein. In thissquare hole isa bar p carrying a loose roller q adapted to bear againstthe inner surface of the tread of the wheel. i The lower end of lever Lis attached to alug on the frame Aby means of a spring r. The object ofthis spring held lever and its attachments is to yieldingly keep theapparatus in contact with the car wheel when the car has gotten someheadway, and thereby draw the apparatus after the ear. The harp is adjustable with reference to the arm n and when set, it may be secured bymeans of a thumb screw s which passes through a slot t in the arm.

The operation of the invention is as follows: The apparatus is pushedagainst one of the Wheels of the car to be moved, or moved forward untilthe said car Wheel is held tightly between the corrugated taperedrollers E. The lever L and its roller q are then adj usted,

and the apparatus is in a condition for use. The hand bar I is thenraised and lowered, and

in the latter movement the pawl H engages with the ratchet teeth d andthe tapered rollers E'are thereby rotated, and the car wheel turned. Atthe same time the apparatus `is forced forward or toward the car wheelby means of the roller J which is revolved by the teeth b and lo.

I do not restrict myself to the employment of the lever L and itsattachments for the purpose described, as numerous other contrivancescan be arranged for the same purpose.

In Fig. 2, I have shown in dotted lines, an ex- IOO tensible spring barM attached tothe spindle B which is elongated for the purpose, and withits outer end hooked over the Vaxle N of the car wheel. Fig. 5 is a sideView of this 5 extensible spring bar.

I claim as my invention- 1, In an apparatus for moving ears, a pair oftapered corrugated rollers between which a Wheel of the car is gripped,and suitable gearing for effecting the revolution of the said rollers,substantially as specified.
